The exhibition was a poster action of the International Triennial of the Stage Poster in which noted artists from different countries and continents participated. It consisted of 30 posters denoting the letters of the Bulgarian alphabet. Each artist is the author of one poster-letter assigned by drawing a lot during the session of the international jury of the Fifth Triennial held in October 2007 in Sofia. One of the poster-letters - "Ü"- has been created after a competition among young Bulgarian artists and students. More than 60 projects of artists aged below 35 participated in it.
